In 1882, the National League assigned stocking colors to the member clubs: red for Boston, white for Chicago, gray for Buffalo, blue for Worcester, gold for Detroit, green for Troy, and so on.Starting in the 1970s, with the advent of synthetic fabrics, teams began using more color in their uniforms, notably the Kansas City Athletics in 1963, the San Diego Padres' brown-and-yellow scheme beginning in 1969, and the Houston Astros' rainbow stripes in the mid-1970s.This era also saw the emergence of powder blue as a primary road color, with teams such as the Kansas City Royals, Minnesota Twins, Montreal Expos and Philadelphia Phillies popularizing the look.In the late 1970s, the Pittsburgh Pirates began a trend of multiple combinations of differently colored jerseys and trousers and caps (with the options of black, yellow, and white with pin stripes).From 1976 to 1981, the Chicago White Sox at times had an all-blue uniform, part of a radical style which included a jersey with a large collar, worn untucked—and, for two games in 1976, shorts.Teams such as the Anaheim Angels and Toronto Blue Jays incorporated a 'faux-vest' uniform, featuring contrasting color sleeves to simulate the look.The Los Angeles Dodgers occasionally use the livery of their original identity as the Brooklyn Dodgers, on special anniversaries or occasions, for example such as in honor of the retirement of Jackie Robinson's uniform number 42 throughout professional baseball (on April 15 – the anniversary of Robinson's MLB debut – entire teams often wear 42).As a result, a number of teams began to veer away from wearing gray uniforms on road games, something that was not seen since the "pullover" era of the 1970s–1980s.[6] In 2024, Nike and Fanatics received harsh criticism after modifying the template of each Major League uniform to the new Vapor Premier chassis.The most notable changes included lowering the MLB "batterman" logo below the neck piping (on some teams), shrinking the size of the letters on each player's name, and lack of customization options.These teams feature the club nickname on both the home and away uniforms (since 1900, in 169 seasons – including the Athletics' presence in the city from 1901 to 1954 – the full word "Philadelphia" has never appeared on a Major League jersey).The most famous example is the New York Yankees' classic pinstripe home uniforms featuring the interlocking "NY" logo.On April 16, 1929, the Yankees opening game was cancelled due to rain while the Indians played, becoming the first team to wear numbers on the back.By the mid-1930s every team in Major League Baseball was wearing numbers on the back of jerseys except the Philadelphia Athletics.
